Hi I a beginner with GStreamer, I am clueless about of the behavior and role of some GStreamer elements.
I wrote a pipeline to get transition effect between 2 avi videos, it works fine but the sond, there's no sound at all.
I was told to put an avidemuxer, I've been working around with it without luck.
I put it between the queue and the gnlcomposition,it doesn't work, then I put after the queue. I wonder if some decoder is missing.
I tryed to adapt my pipeline to this one:
http://lists.freedesktop.org/archives/gstreamer-devel/2008-October/019240.html, but any adaptation didn't work for me.
I got many kind of errors:
"GStreamer-CRITICAL **: gst_pad_link_full: assertion `GST_IS_PAD (sinkpad)' failed"
or
Segment Violation
Thanks a lot,
Rossana
This is the pipeline I need to adapt to hear the sound:
bin
-----------------------------------------------------------------------------------------------
alpha --------------------
|----------videomixer ------------fmpegcolorspace
smptealpha ---------------
^
|
-----------------------------------------------------------------------------------------------
|
Controller // it controls the start-duration property of smptealpha
composition
--------------------------------------------------------------------------------------------------------
gnlfilesource
| |gnloperation| // contains the *bin* described above
|
gnlfilesource
--------------------------------------------------------------------------------------------------------
gnlopetation contains the *bin* described above
gnlfilesource, one for each video
pipeline
